There are thousands of celestial bodies including asteroids, meteors, comets, black holes and UFOs about which we don’t know much. The impact of these celestial bodies can harm the Earth and the whole galaxy. Scientists, researchers and astronomers are studying the activities of space but are not able to solve many mysteries. Now, the scientists from the European Space Agency have announced that black holes produce huge ‘UFO’ outbursts which are so powerful they can change the shape of entire galaxies, reports metro.co.uk.
It is to be noted that the UFOs are actually ‘ultra-fast outflows’ of highly ionised gas which travel at speeds up to 40% of the speed of light. According to a new report, astronomers spotted this ‘wind’ blasting from a supermassive hole at the centre of an active galaxy called PG 1114+445.
“These winds might explain some surprising correlations that scientists have known about for years but couldn’t explain,” said lead author Roberto Serafinelli of the National Institute of Astrophysics in Milan, Italy, who carried out as part of a PhD at the University of Rome.
Giving up an example, Roberto Serafinelli said, “We see a correlation between the masses of supermassive black holes and the velocity dispersion of stars in the inner parts of their host galaxies.”
“But there is no way this could be due to the gravitational effect of the black hole. Our study for the first time shows how these black hole winds impact the galaxy on a larger scale, possibly providing the missing link,” he added.
Importantly, the supermassive outflows have a huge effect on the interstellar matter surrounding holes and sweeps it away like a snowplough. It can be involved in the formation of stars.
It is worth mentioning here that the scientists already knew about UFO blasts. According to the ESA, the new discovery relates a different type of outflow that has the speed of a UFO but the properties of a slower outburst called a warm absorber. Interestingly, these gusts of wind have been spotted at least six times by the researchers.
ESA said, “Supermassive black holes transfer their energy into the surrounding environment through these outflows and gradually clear the central regions of the galaxy from gas, which could then halt star formation.” “Galaxies today produce stars far less frequently than they used to in the early stages of their evolution,” it added.
“It’s all very new science,” concluded Roberto Serafinelli.
